Corrects an issue causing an unexpected quit in OS X 10.5
after changing the scope timebase (via the Time Base Expansion
control). If you don't encounter this issue, or don't use
the Time Base Expansion control, you don't need to install this
update; a certain optimization has been removed compared to 4.27,
and 4.28 will perform slightly more slowly than 4.27 on PPC machines.

Installer includes Mac the Scope 4.28 and Waavebox 1.73,
documentation and support files.

Installs the time-restricted demonstration version. Unrestricted
software is installed with this same installer and a Version
4.1 or later activation code. Note: an Internet connection
is not required to install or run Mac the Scope.

The iTunes 7.0 update has introduced several
significant cosmetic problems in the display of the TechRTA visualizer
and its preferences panel.Changes made
by Apple to iTunes have resulted in compatibility issues with
the TechRTA Visual Plug-in. The latest version of iTunes (7.5)
has eliminated many of the issues, however.

To summarize:

The TechRTA Visual Plug-in has full compatibility
with iTunes before iTunes 7.

The TechRTA Visual Plug-in will run on iTunes
7.5 (not other versions of iTunes 7), with the following limitations:

1. The preferences panel (Options...) of the
TechRTA Visual Plug-in won't update properly when the tabs of
the preferences panel are clicked. To see other options, first
click the desired tab, activate the visualizer, then deactivate
the visualizer.

2. The fullscreen display is interpolated
from a smaller version, causing the text to appear jagged.

The TechRTA Visual Plug-in won't be recognized
in iTunes running on an Intel processor Mac. We haven't yet finalized
plans to update the plug-in to address this or the above issues,
but expect to do so soon. Note that the visualizer as originally
released has been compatible with iTunes all the way back to
1.0 (including Mac OS 9).

We urge customers to try the plug-in in Demo
mode, to be certain that the performance is satisfactory on their
system.

Set your player to a low volume level before playing
the files.Loudspeaker
damage will occur if the volume is set too high!

1 kHz Burst: This is an MP3 file with short
(100 millisecond), full-scale waveform pulses with a frequency
of 1 kHz. Useful for comparing the transient response of the
TechRTA plug-in to the iTunes built-in RTA. (Fast transient response
is essential if the RTA is to track the musical signal in a meaningful
way).

16 kHz Tone: This is an MP3 file with a continuous,
full scale tone with a frequency of 16 kHz. Useful for comparing
the frequency response of the TechRTA plug-in to the iTunes built-in
RTA. (Extended high frequency response of the RTA is useful for
examining the loss of high frequencies resulting from encoding
MP3s at low bit rates). This file is bigger than the 1 kHz file
because it was encoded at a higher bit rate (to preserve the
16 kHz!) :)

4.0 includes over two dozen significant additional
features compared to 3.0.2, and performance enhancements.

This is a free, Complete - level upgrade from 3.0x (including
all NetBoot and AppleShare Enabled software configurations).
Just use the same instructions included with the 3.x Activation
Code to install and validate 4.0.

This file (m4pr.hqx) is the installer
application for the evaluation (demo) version of both Mac the
Scope and Waavebox. It also serves as an installer or updater
for users who have purchased an activation code for Mac the Scope,
Waavebox, or Waavebox Lite.

Activation codes purchased for Mac the Scope 4X (OS X)
will work with Mac the Scope 4.0.
